Smut, actual and implied ahead. You've noticed this story was rated "M" right? Also this is envisioned as happening after - a few years after? - chapter 47 where Kaname and Yuuki left together and Zero was seen carrying his brother's body. The vow is there for Zero to follow and destroy them, but he and Yuuki had shared that last kiss, that last offering of blood. It spoke volumes of his longing for her, and maybe, of hers for him...

"HE'S ASLEEP, Yuuki. Don't wake him."

Kaname sighed as Yuuki ignored him and entered the room anyway. He knew she'd missed him. He'd missed him too, but he would be awake in a few hours and they could all meet up later. She'd just interrupt his sleep and make him crankier. But even as he thought this rationally, Kaname still found himself entering the room behind her. He stood in the doorway, as if reluctantly drawn, to watch as Yuuki walked to the bed and, after seeming to listen and watch for a while, mounted the bed and curled up into Zero's slumbering form, nuzzling him impatiently. Kaname watched, the usual forbidden warmth spreading through him as he saw Zero stir then awaken. A hand came up automatically as he rolled to be more comfortable as Yuuki lapped at his tender neck, cupping her head as he'd support something precious, something fragile, even though that wasn't entirely true. His eyes opened sleepily, and he frowned as he tried to direct his mind to the present. The house had been empty when he'd fallen asleep earlier.

"You're back." Zero said stating the obvious but conveying just how happy he was that was the case. Kaname stayed still in the shadows but he could see that Zero was searching for him in the dark, as if some other part was missing. Kaname's heartbeat accelerated at just this small act. No matter how many times he tried to let himself believe they were both his, and he belonged to them, sometimes he couldn't make himself rely on it. Zero's roving gaze despite having Yuuki in his arms touched him profoundly, but he didn't move though, even as he saw Zero still hadn't seen him. He didn't want to intrude as yet. He wanted Yuuki to have her way first. Still...

"Where's Kaname? Didn't he come back with you?" Zero asked as his eyes slid closed.

"He didn't want to wake you. I knew you wouldn't mind."

"He can be so silly sometimes. Treats us both like porcelain dolls. Are you going to bite or just make me crazy?"

"A bit of both." Yuuki teased, lifting her head to smile, allowing Zero to see her fangs. Zero's eyes flew to her small mouth, seemingly mesmerised by what he found there. He lifted his head and pulled her beautiful taunting lips to his own.

Kaname watched them kiss, them both giving way to the sweet sensations he knew they would feel. He watched as Yuuki fisted Zero's hair to hold him to her mouth as he expertly licked and sucked her sensitive lips and her exploring tongue, allowing her to suckle the wound she had "accidentally" made in his lip. Kaname own body came to high alert at just that hint of Zero's blood in the air, fangs descending easily in preparation. They had been away for a couple weeks. Kaname was a little starved for Zero's... affections...

Yuuki chose this moment to rake her nails along Zero's arm, making him wince and jerk away.

"Yuuki!"

Yuuki giggled and moved to lick at the wounds, her eyes looking up into the gloom to hold Kaname's. Kaname watched rapt as she cleaned the wounds slowly of the blood, her face showing her thorough enjoyment of this. But as if to emphasise, she allowed a low moan. Zero's breath caught at this. She found herself lifted and thrown onto her back, her legs parted urgently, Zero's burgeoning groin pressed to her heat.

"You know what that does to me, you minx..."

Yuuki laughed and pushed both hands into Zero's pyjamas' bottom, her small hands seeking and finding, beginning to massage exactly as she knew he couldn't resist. Zero quaked and collapsed onto her chest, his hot breaths warming the material of her suit, just over her left nipple. Yuuki's eyes fluttered closed as her body suddenly wished for a bit more than this good-natured teasing.

"Geez, Yuuki...!"

He was on his back with Yuuki ignoring his protests. She straddled him, covering his jerking groin, rubbing against him impatiently as she unbuttoned her jacket and discarded it, before pulling impatiently at her scarf. Zero sat up and grabbed her to him. Using his teeth he ripped a button off the undershirt, then another and another before nudging the thin cotton away from one swollen, aching breast, still housed in its lacy casing. Zero, though, liked what happened when he held her and ran his teeth over the clothed, stiffening nipple...

Yuuki's breath caught, her body sinking onto Zero's groin impatiently as she ground her aching, moist heat into him. Her head lolled back exposing her delicate, white neck, the tempting vein, her eyes closed as Zero ignored her painful tugging of his hair, unheeding of the wordless plea to stop his insistently, hot sucking of her tender breast, to released her from his vice like grip so she could remedy the already mind-blowing urgency between her legs. Zero held her hips and body so tightly she couldn't even relieve herself, couldn't even rub her throbbing juncture onto his...

"Let... me go..." Yuuki gasped, her lungs vibrating from the insistent need that had taken her body over, "Zero, please. I need you to..."

"Shhh... Not yet. I haven't even said 'hello' to the other nipple. So rude of me..."

Zero slid his tongue along the "V" of her bra, sensuously skimming her hot skin, and descended slowly onto the other straining, sensitive peak...

"AAHHH!!! Dear heaven!!" Yuuki cried out as the sweetest ache shot from her small breast, right through her to throbbing core. She could feel the dampness between her legs spreading, almost as if she'd had an unfortunate accident. Zero's brows knitted as his own body galvanised from Yuuki's wanton expressions. The scent of her arousal was heavy in the room and he could feel how prepared she was for him, even without having touched it, even without having fully removed their clothes. He began to think of how hot she would be, how greedy she would be, swallowing him whole, one devastating inch at a time...

Zero felt the bed move and he looked up quickly to see a dark figure descend on Yuuki's open mouth quickly, covering her desperately seeking lips with an urgent, though gentle kiss. Kaname could never stand to see her like this. Zero paused as he saw Kaname, uncertain as to whether to continue. How he made love to Yuuki alone was different to when Kaname was present. Some things he did to her he preferred not to in... company. Yuuki was Kaname's princess. For instance, he could never say no to her. Not like this...

"Stop teasing Yuuki. She missed you too, you know."

"I know. But I couldn't resist..." Zero trailed off, still quite uncomfortable sharing his darkest fantasies with Kaname. Sure, they shared a complex relationship Zero had only relatively recently been persuaded to participate in. He'd loved them both, but this... Yet he had been persuaded, had been worn down by their patience and love and their very high level of comfort with this rather disturbing situation. They'd tricked him, drawn him in carefully, meeting him separately and then one day Yuuki had joined Kaname and him while they were... um... quite committed. Kaname hadn't even skipped a beat while Zero's face had burned in shame. There he was, laid bare, Kaname quite enthusiastically driving in to him as Yuuki slides in between them, without an ounce of self-consciousness, kissing Kaname passionately while planting herself without too much preamble, onto Zero's stiff...

"The last time you did that she broke your arm." Kaname reminded gently, as he began to remove his clothes, leisurely, even as his other hand caressed Yuuki reassuringly. He behaved as if he had all the time in the world, but he watched Zero's eyes follow his movements, especially when his fingers reached the lower buttons on his shirt and started on his pants, greedily drinking in each exposure of pale, flawless skin. He could see Zero's mouth watering as he watch him. God, he loved that about him...

"Zero, Kaname, somebody..." Yuuki whined as the two men seemed to zone out on her. Zero's loosened grip gave her the room to wiggle her hips desperately. She moaned as her sensitive flesh massaged Zero rock hard groin, offering her some relief but leaving her wanting more. She pushed away Zero's arms and shoved him back on the bed. Zero went willingly letting the two lead as he always did when they were together like this. Yuuki pinned his arms over his head and bent to kiss him as she tugged at the rest of her clothes. She felt as if she had to have him or she'd go nuts. She wanted to sink him deep inside her until she had milked every inch dry. But she paused as warm hands stilled her frantic one and carefully undid her bra and skirt before sliding them off leaving her briefs for last. Yuuki trembled as her brother's large hands cupped her breasts and his warm mouth began to kiss her spine. Slowly, deliberately, going lower and lower to her tailbone and when he came upon the lacy slip of fabric...

"Kaname!! Kaname...!! Dear...!" Yuuki gasped as the briefs ripped loudly and a tongue began to explore her secrets, licking ravenously, delicately yet insistently. Yuuki screamed as her eager bud was hauled into a mouth and alternately sucked and rolled by a restless tongue. She fell forward onto Zero who was watching this with rapt attention, his hands still pinned, but Kaname held her hips up firmly as he continued to destroy her sanity. Zero began to shudder, his own body primed for release as Yuuki writhed on top of him, her scent driving him crazy, his longing to push inside her and screw her senseless seemed more important than his very life. Zero tugged at his hands as his hips bucked uselessly. Please, he begged, please...

Kaname was watching Zero's tortured face was much interest, his own body protesting at his iron-clad restraint. Both Yuuki and Zero excited him. Their being in a bed together with him blew his mind. He still fantasised about that first time when he'd been inside Zero and Yuuki had joined them. He didn't expected to be overwhelmed the way he had been. He knew it would arouse him but when Yuuki began to ride Zero and Zero had thrown his head back and arched, his fingers tearing the sheets...

"Kaname!" Yuuki cried as his tongue brought her to her third orgasm. Kaname pressed its entire, considerable length deep inside her, moving it relentlessly, relishing her strong contractions on his tongue as he fingered her throbbing nub. Yuuki stayed for a while, moaning as she savoured that miraculous tongue beating gently against that sweet, sensitive spot before rolling to a side, nearly spent but aware enough to notice how Zero was shaking with need. Her hands caressed his heaving chest sympathetically as she fought to regain her lucidity, propping herself up in preparation to assuage it. But Kaname was there, laying his body languidly on top of Zero's, pressing into him so nothing was left to the imagination. Yuuki dropped back onto her side but curled into Zero's, lifting her head to kiss Kaname quickly, but noting Kaname's eyes didn't leave Zero's face as he submitted to it. Yuuki chuckled.

"I know that look Zero. You're in for it now." Yuuki warned, as the same hand that had manipulated her ruthlessly just now reached up to caress Zero grey mane, brushing it away from his face affectionately. Yuuki just watched, always awestruck by how her brother related to Zero. As if he was beyond fragile. Zero though wasn't having it. He tossed his head impatiently.

"Kaname, let me up. I want to..." Zero's eyes lit on the juncture between Yuuki's legs in a silent entreaty which Kaname ignored.

"I missed you too." Kaname muttered interrupting, lowering his head to capture Zero's lips, tugging roughly at the lower lip before deepening the kiss. Kaname parted his legs and lifted himself, delving his hands beneath Zero to hold him to him, to run his hands insatiably over his skin. Zero whined in bitter disappointment as one obsession was lost but it was quickly replaced by another. Kaname... His kisses... they were impossible to resist. Especially when he was in this mood.

"Kaname!! Slow... Oh shit!!" Zero bucked and writhed as Kaname dipped lower to his sensitive neck, raking, nipping, biting. Zero threaded desperate unheeded fingers into his hair as he tried to pull Kaname away, but to no avail. Kaname was quite lost, unable to stop himself. He pushed lower, teasing Zero's rosy tender nipples into stiff buds, before sucking the hell out of them, his rough tongue laving the tips in a way calculated to...

Zero bucked off the bed and half rolled but Kaname pushed him down, one hand holding a shoulder. Yuuki slid up to Zero's head and trailed fingers down his face to his swollen, bruised lips before lightly kissing them. She then pulled Zero's face into her breasts, hoping to comfort him, still knowing there was none to be had. Zero pulled away from her as Kaname began to lap at the plane of his stomach, as fingers ventured lower to his tightness. Zero tried to escape. This had happened that one time, but not since. He hadn't like it. He didn't like doing this in front of Yuuki. His pride burned to have her watch him like this. He was her man. At least he wanted to be. Sure, there was Kaname, but when they were alone she looked to him for comfort and satisfaction. He whispered his love for her and swore to protect her. They fitted together perfectly as a couple should and he prided himself with making her cry his name as he took, as he possessed her. He couldn't handle this. Her seeing how easily Kaname could pull him down and undo him, making him cry for him just as she would. Possessing him just as he would her. He was her man. He didn't want her to see him weak and trembling as Kaname cleaved him, over and over...

"No. Kaname... Not now..." Zero pleaded, pushing hard at Kaname's shoulders.

Kaname groaned, his brow knitting in annoyance at the hitch in his plans. Seeing Zero like this made him hunger for him like nothing else. His body protested painfully at being thwarted and Kaname lifted his head in askance. When they were alone Zero would already be spreading his legs, pushing his head lower, begging him to take him in his mouth. Zero was unbridled in his lovemaking and this thought had made Kaname almost crazy at the look on Zero's face, as he had teased him. That look promised an earth-shattering experience.

"What is it?" Kaname rasped, though his finger came to his mouth for a bit of lubrication before returning to the tight pink ring that when rubbed insistently had Zero...

"OOhh Godd!!" Zero panted. Just his touch! That's all it took...

Kaname forgot his concern as Zero jerked and grabbed his hair, pulling him down to lavish attention on his stiff rod, which Kaname didn't need an engraved invitation to do. He, steadying himself, dipped to Zero's smooth tip and slid slowly over his engorged flesh, simultaneously sliding his finger into Zero's opening, twisting his finger until he was rubbing that spot just on the front wall, the one that always dissolved all of Zero's protests. When Zero was seated deep inside his throat, Kaname lifted his head and pushed down again, roughly, mercilessly, swallowing over the near purple tip before climbing to plunge again. Zero's hot core tightened around his fingers. Kaname knew he was coming...

"Ooohhh Shit!!!" Zero cried as his body convulsed, shooting his seed into Kaname's throat, tugging greedily at Kaname's buried fingers. Yuuki dropped a kiss on Zero's widened mouth as he panted, eyes closed, his body shuddering as Kaname continued after a slight pause, pushing Zero to where he knew he could go...

"Ahhh Kaname!! Unggh!!" He cried again as his body was gripped by another climax. Zero curled to a seat, trying to make Kaname let up, but his hands were pushed away dismissively, Kaname's grip tightening as his head bobbed, his eyes closed, listening to everything about Zero. Concentrating... Before long Zero fell back on the bed and arched, his body coming apart in yet another orgasm.

Yuuki's smile was gone. This was seriously hot stuff. She longed to join in, her body coming alive again as she watched her husband torture Zero exquisitely. She left her vigil by Zero's side and crawled around behind her brother. She reached around him and grabbed his leaking length, squeezing then slowly rubbing it between her hands, all the while raining kisses on his sweaty back. Kaname moaned around Zero's taxed flesh and pulled away, shrinking into an almost defensive ball as his mind threatened to shut down. He groaned pitifully again as Yuuki rolled him onto his back and descended, sucking, lavishing as she'd see him do to Zero. Kaname gasped and opened his eyes, one hand cupping her cute face, but he looked around determinedly to search for Zero who had shrank away to the headboard, still trembling, his fingers combing back his hair as he tried to calm down. Kaname growled softly, his eyes narrowing in protest. He certainly didn't want that.

Zero heard the growl and looked up, meeting Kaname's intense, dark gaze. His eyes widened as he read the intentions there and he moved to scoot off the bed, looking to beat a hasty retreat. Kaname really was in a strange mood.

"You two continue. I'm going to..."

Zero found himself yanked back on the bed, suddenly a tangle of limbs. He tried to right himself but was rolled onto his stomach.

"Kaname!! Don't!!" Zero panicked, pushing at Kaname's hands. He was going to... No!

"Zero... I know but... God, I want you so much..."

Kaname parted Zero's firm cheeks and began to use his tongue to full advantage, licking the insanely sensitive ring vigorously before teasing the entrance with the tip of it, darting in and out quickly, while Zero writhed involuntarily beneath him, hips pumping mindlessly. Kaname didn't hold off for long, as Zero's heat called to him. He raised himself and slotted himself home, crying out as if his body had finally reached its highest aspirations. Zero winced as he was filled by a long hard length, the hot flesh dividing him quickly without a chance for adjustment. Zero buried his face in the mattress, feeling like he was dying inside. He hid his face as Kaname began to move, beginning the glorious friction that he knew they both could never get enough of. Zero sobbed as he felt his body respond, the sensations travelling quickly the length of his aroused frame. Yuuki. She would see this. Was watching as Kaname dominated him. Sure, they were lovers. They shared each other. But doing this like this, with her watching was like losing to Kaname. He would lose her respect and then, he was sure, eventually her love. He had explained this to Kaname. He had refused to speak to them for days after the first time, feeling as betrayed as he did. He couldn't even face her. But, eventually they'd made up, with Kaname agreeing to wait until Zero was ready. It didn't happen again and Zero had relaxed while they shared their bed but now. Now... Tears came to his eyes as Kaname rode him, his breaths erratic and loud, mingling with the sound of slapping flesh as he pushed deep and hard, Zero's hot, tight, velvet sheath hugging and seducing him. How could Kaname do this knowing how he felt? Was it deliberate? The cruel bastard...

"Zero... Zero look at me," came the sweet voice. Zero buried his head more, hoping his tears just merged with the sheets. The final indignity, her seeing him cry while like this. Yuuki panicked.

"Kaname! Stop!! You're hurting him!!"

"What?" Kaname opened his eyes and stilled, suddenly uncertain. Suddenly afraid... "What is it? What happened? Zero?!"

They rolled him over as Zero fought them both, hiding his face in his hands. Yuuki pulled at them gently and firmly, her face angry.

"You were too rough!! I keep telling you to be careful!!"

"But I was careful! We've been much rougher than that with each other! I don't understand what happened!"

"Well it's obvious you weren't! Dammit, I was looking forward to this for weeks and you ruin it with your over-sexed selfishness! Didn't Zero say he didn't want to? You should have listened instead of wanting your way all the time!!"

"Not want to?! But Zero loves this! His only problem is when I do it in front of you...!"

Kaname came to an uncomfortable halt. He and Yuuki looked at each other as realisation dawned. Kaname smacked his head as Yuuki stopped tugging at Zero's hands, the hands Zero was wishing were bigger right now so they could swallow him whole.

"Zero. I'm sorry. I forgot..." Kaname began miserably, but Yuuki stopped him.

"Would you go get us some ice-cream, Kaname? You know, Zero's favourite? I think we're out so you'll have to go to the store."

"I don't think I should leave Zero like this..."

"Please? And get some cones so we could eat in the gazebo near the lake. I'll sit with Zero until you come back."

Kaname lingered a little longer, uncertain what to do. Whenever Zero was upset he normally held him and kissed him until he stopped being upset, but it was obvious Yuuki wanted to handle this. Reluctantly he stood and began to pull on his clothes.

"Alright. I'll be back in half an hour."

Kaname gave Yuuki a look of warning to be careful and left closing the bedroom door. Yuuki waited a little while and slid down to lie next to Zero, resting her head on his shoulder. She stayed like that for a while until Zero lowered his hands, feeling very silly to be there with his face covered hiding from Yuuki.

"I know you think I'm..."

"That's just it. You don't know what I think." Yuuki interrupted, her hand moving to run it up and down Zero's chest, her palm rubbing him soothingly.

"Well I can guess..."

"Do you know, ever since that first time I've been thinking about doing that again? Of watching Kaname and you together. I fantasise about it. Dream about it. Those times we make love and I touch you there and you tremble I think about Kaname slowly pleasuring you like that. I like it. Just now, I came as soon as he was buried inside you and you released a low moan and went limp as he began to move. God, I think you are hot like that. I feel close to you because you know how it feels to have Kaname driving into you like that..."

"Like some woman. Perhaps that's it. You identify because you don't see me as a man!" Zero pushed at her and sat up getting to his feet. He knew it! He knew...

"No! That not it at all! Zero! Wait!" Yuuki was suddenly in front of him stopping him from leaving. Zero's stance became defensive as he began to think of a way to get pass her.

"You are trying to get me to believe that when Kaname dominates me like that you don't think less of me?! Why wouldn't you?! He's the man you've wanted your whole life. I've always been in his shadow. Maybe... maybe you've always thought less of me..."

"You idiot!! You're always insecure. Always!! No matter how much I love you. No matter how much attention I give you or how often we make love, or Kaname makes love to you, you always come back to this! You want me to choose you over Kaname. That's the only way you'd feel whole, at peace. But it is not going to happen. I love him. Just as much as I love you."

Zero turned away and headed for the window and was headed off again. Yuuki's angry aura was escaping but Zero ignored it, quite used to it by now, though he felt queasy. He stayed still, deciding to wait her out. Kaname would be back soon. Yuuki saw this.

"Zero, you'll never win. But, you will never lose either. Don't you see? You are indispensable to me. When you are unhappy, my heart breaks and when you feel pleasure my heart sings. All I saw was my Zero enjoying himself with my other most important person. I was doubly happy and extremely turned on. The only person thinking less of you, was you."

Zero looked towards Yuuki's earnest gaze and sighed, running his hands through his hair. Was she right? Was he being a fool? It was just that, he knew, if he was forced to choose, if he could only have one person, he would have chosen her. Yes, he loved Kaname, but he was Kaname. He could take care of himself. He would find a way to move on. Yuuki was more precious and knew him like no one else. In this frame of mind Zero couldn't countenance their equality in her eyes. Kaname was the vampire prince and Zero was the ex-human hunter. Kaname was stronger, richer and more powerful. There was no contest really. Not to Zero. Because Yuuki and Kaname weren't completely equal in his.

"Stop that, Zero. Stop doubting me, stop doubting yourself. If you really want to know, that is where you lose me. When you lose that belief in yourself and in your right to live in our world. That is when I wonder if we made the right decision. If we should have seen pass what kept us as natural enemies. When you look miserable and unsure. Like this..."

"No! We did make the right decision. Yuuki, I love you and I love Kaname. There is no question of that..."

"Then act like it. Come here and welcome me home and when Kaname comes back welcome him home too. You should have seen how eager he was to see you. My poor baby. I know he's probably very distracted from only getting a taste of that devastating ass of yours..."

"Yuuki." Zero interrupted, a dangerous tone to his voice as he began to back her towards the bed, "I know I am very distracted by not getting a taste of yours. Where were we before Kuran took over the show as he always does?"

"I think... I think you were about to... Oh!! Ohhh Zero..."

KANAME started the car and continued down the drive, a contented smile to his lips. Maybe if he hurried he could come back to continue where he'd left off.

Thanks so much to Blackened Wing's "Five Hundred Miles" ending that had me hungry for more – and may God help me – threesome with YUUKI in it. YUUKI!!! I am still in shock...
